Answer:
The ride took 7 1/2 hours to complete.
Step-by-step explanation:
If the bicyclist is going at a constant speed of 6mi/hr it would take 7 1/2 hours to ride 45 miles.
6*7 1/2=45
2) Find the area of a parallelogram with a height of 8 inches and a base of 14 inches.
A=bh=14·8=112in²
3) Find the surface Area of the rectangular prism with a length of 15 cm, height of 7 cm, and width of 5 cm.
A=2(wl+hl+hw)=2·(5·15+7·15+7·5)=430cm²
4) Find the volume of the following figure:

5) You are wrapping a cube shape present that is 9 inches tall. How much wrapping paper will you need to wrap the entire present.
SA =
= 9x9x9 = 729in²
6) A truck has a trailer that has a length of 13ft, a width of 6ft, and a height of 8ft. What is the volume of the trailer?

Answer:
17
Step-by-step explanation:
6 x 2 = 12 so 12 + 5 = 17
Dylan would have to pay $17.
Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
